A cheaper way to get technical SEO data from your website.
I was pleased that it had lots of helpful data when looking at the technical data for my website.
I liked that there was a trial and that it was much like the more expensive tools out there but for a much smaller price. I think this would be great for junior or beginner SEO specialists.

Simple, practical at a low price
Ok, it’s not a screaming frog. But it doesn’t have to be at this price.
SEO Checker is a cheap practical tool to quickly get a good overview of all titles, descriptions and headings of a website. Just crawled 775 single pages on a website... works for me and maybe the developers will extend the program in the future.

Great app for creating a sitemap
This is very handy app - for creating a sitemap, and enumerating all of the pages (e.g. if for some reason they are excluded from sitemap.xml).
Please continue adding features to the app!

As a complementary tool to others that I usually use to do seo analysis of my websites, it has been very useful to find aspects to improve, especially in the definition of h1 and h2 tags; and allowing complementing with other Google tools in its contextual menu also makes my job easier.
